To all whom it mag concern: I Be it known that I, Aia'rnonr ANIA, a subject of the King of' Italy, residin at Coronmin the county of Queens and, tate of New York, have invented new following is a specification.

This inventionrelates to new and useful improvements in aeroplanes, and has for lts primary object to p the landing of a machine from a flight may be facilitated. i

A further object of the invention is to provide a device of this character'which will efiectively right the machine and cause the same to assume a proper horizontalposition in landing.

A further object of the invention is to I provide a device of this character in" which $9" the shocks and ars incident to landing of aeroplanes is entirely eliminated;

The device is an improvement over the device shown in Patent No. 1,285,893, granted to me, andis adapted to use equally well connection withaeroplanes of all types;

Referring to the drawings Figure 1 is a side view of. a portion of an aerop' ane showing the device n place thereon.

erably of the, biplane type, the upper and lower planes'being' designated by the referonce-characters 6'and'7 respectively,

Mounted between planes 6 and 7 are two-tubu ar members 8, the upper end of each of which is closed as at9, the lower end of each of these'tu bular members being open and adapted to register with its respective opening 10 in the lower Planet. r The reference .character'lldesignates the traction wheels of the device, and said wheels are mounted on the opposite ends of the axle l2. Projecting upwardly from saidaxle 12 in spaced relatlon are twofrigid rods 13, these rods being long-enough to extend.

Referring more particularly to the dr'aw-v ings, the reference character 5 designates the fuselage of an aeroplane, which is prefthe free inner on member- 24 is a The operationof the device is as fol 1lows:-'---.

the up er and lower or taken up by to assume a horizontal Patented Au -0 alioii secured'to the under face thereof is a loader member which is provided with two spaced openings 16 adapted to register with the spacedopenings in the lower plane 7 and the open lower end of the tubes 8.

Surrounding each of the rigid members 13 1s a coil sprlng 17 the lower end of which is adapted to engage the axle 12, the upper end of each of said springs enga 'ng the under face of the buffer plate 15 fil between the upper end of each of the rigid onnted members 13 and the closed end 9 ofthe tubular members 8 is a coil spring 18 -which is adapted at times to compression under theaction of engagement of the traction wheels 1 11 with the ground when landing.

By this construction, it is the body or fuselage and the p use are resiliently mounted withrespect to thetraction wheels andthat all shocks and jars attendantthe landlngof theniachine are read- 11y taken up and effectively absorbed.
